The special area of forebrain controls the human behavior actively

It seems to be the place of responsible for self-control in the braining that the cortex of forehead leaf carries the outer district.
(The picture is offered: ToddHare/CaliforniaInstituteofTechnology) While prohibited to eat, do you want to eat a stick of French fries or a cube sugar? One announces to new research that self-control pays, how people struggle against appetite to depend on a small activity of an area in the forebrain. This research results, in order to understand better some is harmful to the behavior - -For example eat immoderately, drink and smoke - -Have opened a gate.
Behavioral researchers have known for a long time self-control is an important component of the decision. However, they know little about the brain area correlated to this. When a person makes the difficult choice, several areas of the forebrain demonstrate very high activity, but how the scientist has different views to work in coordination to these areas! For example how is brain until short-term candy of chocolate lure and weigh between the one long-term the intersection of health and interests of green salad together?
Nowadays, the researchers of California Institute of Technology, Pasadena of U.S.A. think they have already found the answer to the problem. The scientist recruits 37 diet keepers succeeding in reducing weight or maintaining the weight. These volunteers can measure the functional magnetic resonance imager (fMRI) that the brain moves about to enter one after being in fasting for 3 hours . In the instrument, these experimenters will watch to 50 different food pictures, and carry on the assessment in a range to five o'clock to health grade and delicious grade of the food according to their judgement.
Researchers have chosen to be chosen as a kind of neutral food by diet keeper in two aspects subsequently, and require experimenters to choose between this kind of food and 49 kinds of other food. Though all experimenters brag about oneself " The diet keeper " ,But probably half of person has thrown self-control beyond the highest heavens, and then choose those more delicious food; Meanwhile, half the persons will still choose those healthier food.
This kind of difference seems to relate to the fact that one is called cortex of forehead leaf to carry the brain area of the outer district. Only when the volunteer chooses a kind of healthy food in a great deal of more captivating food, thought in the area related to cognition and memory and will be lighted in fMRI before this. In other words, it seems to act the part of mother concerned about we of a neural edition to carry the outer district - -Tell us to eat some peas before eating the dessert after the meal. The neuroscientist ToddHare of California Institute of Technology who presides over this research says: "Good at the person of self-control and not in charge of a difference between one's own person well, may lie in activating the cortex of forehead leaf and carrying the ability of the outer district. " Researchers have reported this research results on American Science published on May 1.
The neural economist PaulGlimcher of New York University thinks, Hare has " already or found the area that can control the health in the brain " . Glimcher points out, this research results pass and show some behavior problems to researcher - -For example eat or drug dependence immoderately - -In the area of origin in the brain, thus can offer the new method for treating these diseases. He says: "I am really very optimistic, we are in the starting point of a frontier. "
